Miller, I always read your posts, like I do for several others. I bought a double hammer gun in ITALY. It was described as an 18mm gun. My thought , since it was an 1880 gun, what cartridge was it really for ? Seeing the American cartridges described in millimeters made me think there was an obvious answer.
